Although the Demon God’s strength before him was formidable, there were many challenges in trying to slay it.

But Xu Wendong felt no ease in his heart.

On the contrary, his fighting spirit was even more exhilarated!

Only by slaying such a powerful existence could he truly demonstrate his power and feel a sense of accomplishment.

With this thought,

he let out a low roar, clenched his fists, and launched a fierce attack at the opponent once more.

His fists were like mountains, brimming with world-ending energy, distorting space violently wherever they passed, giving the impression they could annihilate everything at any moment.

The Demon God was forced to retreat under the typhoon-like force of Xu Wendong’s punches, its massive, mountainous body unexpectedly unstable under the onslaught of energy.

Xu Wendong saw the Demon God’s disarray but did not relax in the slightest, knowing well the devious nature and profound powers of such creatures; this retreat was merely a facade, with a true fatal blow surely lying in wait.

Sure enough, the Demon God’s body was suddenly covered in brightly glowing demon patterns, and a ghostly black light seemed to swallow all life in the world. The demon shadow flickered, evading Xu Wendong’s follow-up barrage with an eerie deftness.

The next instant, the Demon God, wrapped in billowing black clouds and reeking of blood, counterattacked furiously.

Xu Wendong suddenly pivoted, his foot sharply tapping the ground to sidestep using the momentum.

Seeing this, the Demon God’s assault grew more frenzied, spewing black Demon Flames from its mouth. Wherever the Demon Flames touched, earth and stone melted into pus, emanating a charred stench.

But Xu Wendong’s vital energy was as vast as the sea, and the Demon Flames could not approach his body.

"With just my physical strength, it seems difficult to defeat this Demon God!" Xu Wendong’s gaze was solemn, even though he possessed an Ancient Sacred Body and had become a god.

Yet the Otherworldly Demon’s physical form was exceedingly strong, and combined with being an Upper Divine, relying on mere physical strength gave him no chance of victory.

However,

his true power lay not only in his physical strength.

He also mastered numerous Dao Laws.

That was his greatest reliance!

Without further thought, Xu Wendong immediately dissolved his Dharma Manifestation Divine Skills, returning to a normal human form.

After shrinking in size, he felt significantly more agile, especially able to maneuver deftly against the mountain-sized Demon God.

"Die for me!"

Xu Wendong shouted angrily, his voice thundering like lightning across the night sky.

He was like a phantom, appearing in the air above the Demon God, clenching his right fist and smashing it down onto the central head of the Demon God.

Boom!

At the exact moment Xu Wendong struck, a crushing lightning bolt tore through the night, appearing in the Nine Heavens above.

The bolt seemed like divine wrath, merging seamlessly with Xu Wendong’s fist’s force.

In an instant, the fist light burst into blinding blue-white light as if piercing a brilliant gap in the night sky, tearing the space it touched.

The Demon God tilted its head back and roared, its mountainous body trembling, dark mist swirling wildly around it, trying to withstand the one strike infused with the Way of Thunder.

Yet that force surged forward like a torrential Milky Way, brutally breaking through the hastily erected defense of dark mist.

"Crack!"

A thunderous sound echoed as the Demon God’s central head was struck hard, fissures forming on its rock-solid skull, and black Demon Blood spraying out like a fountain.

Each drop of blood corroded the ground, creating deep pits that smoked greenly.

The Demon God, under the intense pain, lashed its long tail like a steel whip, wrapped in black lightning and rolling Demon Flames, sweeping toward Xu Wendong with the intent to tear him to pieces.

Xu Wendong dodged nimbly, light as willow fluff, tapping the void with his foot like a dragonfly skimming water, each step causing the void to quake and the clouds to churn.

"Hmph, still trying to struggle to the end?"

His gaze was cold, hands swiftly weaving complex Seals in front of his chest, chanting ancient and obscure Spells from his tongue.

Instantly, the surrounding clouds gathered wildly, ink-black clouds whirling into a massive vortex, at whose center silver-white lightning snaked and wove into a net, snapping and crackling incessantly as the Source of the Thunder Avenue gathered force.

Seeing this, the Demon God’s massive body retreated rapidly, attempting to distance itself, but Xu Wendong would give it no such opportunity. His hand seal solidified as he shouted, "Fall!"

In an instant, the lightning net crashed down on the Demon God like a torrential downpour, each bolt as thick as an ancient tree trunk, smiting with earth-shattering might.

The Demon God’s body flickered with demon patterns, struggling to resist, but it was like an ant trying to stop a chariot, each lightning strike blackening and smoking its body in multiple places, while demon scales shattered and scattered.

The Demon God roared in fury, enduring severe injuries as it slammed both palms into the ground, cracking the earth with massive boulders rising, filled with Demon Energy, crashing toward Xu Wendong like meteors.

Xu Wendong flashed into the cloud of interwoven lightning, and those boulders, upon entering it, were instantly pulverized by lightning, falling softly as if in an eerie stone rain.

When the Demon God’s offensive paused, Xu Wendong swooped down from the cloud, wrapped in a layer of brilliant blue Thunder Cocoon, like a descending Thunder God, his right fist raised high, with lightning from his fist condensed into a dazzling Thunder Sword, its blade flaring, seeming to cleave heaven and earth.

"Meet your end!"

At his words, he charged at the Demon God with unstoppable force, thrusting the Thunder Sword fiercely toward the Demon God’s vital chest.

The Demon God crossed its arms to block, but upon impact, the violent power of the Thunder Sword shattered its arm bones instantly.

The crackling sound was unceasing, and the Thunder Sword did not lose its momentum, piercing straight into the Demon God’s chest, spraying Demon Blood everywhere, its body swaying and collapsing like a crumbling mountain, crashing deep into the ground.

"Impo...impossible...how can you wield Dao Laws?" The Demon God’s breath faltered, its eyes dimming, leaving only fear and despair.

The sword Xu Wendong pierced into its chest seemed not to cause severe harm at first glance.

But at that crucial moment, the Way of Thunder, brimming with Power of Destruction, erupted within, ravaging its internal organs and Divine Soul.

"My means are beyond your imagination," Xu Wendong stood hovering in the air, the surrounding thunder gradually receding, as a faint cold smile appeared on his stern face.

The Demon God’s gaze was unwilling, then it slowly closed its eyes.

Seeing the Demon God slain, the townsfolk erupted in celebration, their cheers thunderous, many crying tears of joy, for they had not imagined that Xu Wendong would slay an Upper Divine Realm Demon God.

It was undeniably inspiring, giving people hope.

The mighty figures of the Thirteen Immortal Clans were also stunned by Xu Wendong’s actions, clearly not expecting that a Lower God like him would possess such terrifying power to kill an Upper Divine Realm Demon God.

After the shock, everyone was both excited and expectant, as Xu Wendong’s miraculous talent suggested that marrying their Holy Maiden would likely yield extraordinarily powerful offspring.
